Benefit agent containing delivery particle

ABSTRACT

The present invention relates to benefit agent containing delivery particles, compositions comprising said particles, and processes for making and using the aforementioned particles and compositions. When employed in compositions, for example, cleaning or fabric care compositions, such particles increase the efficiency of benefit agent delivery, there by allowing reduced amounts of benefit agents to be employed. In addition to allowing the amount of benefit agent to be reduced, such particles allow a broad range of benefit agents to be employed.

FIELD OF INVENTION

The present application relates to benefit agent containing deliveryparticles, compositions comprising such particles, and processes formaking and using such particles and compositions.

BACKGROUND OF THE INVENTION

Benefit agents, such as perfumes, silicones, waxes, flavors, vitaminsand fabric softening agents, are expensive and/or generally lesseffective when employed at high levels in consumer products, forexample, personal care compositions, cleaning compositions, and fabriccare compositions. As a result, there is a desire to maximize theeffectiveness of such benefit agents. One method of achieving suchobjective is to improve the delivery efficiencies of such benefitagents. Unfortunately, it is difficult to improve the deliveryefficiencies of benefit agents as such agents may be lost do to theagents' physical or chemical characteristics, or such agents may beincompatible with other compositional components or the situs that istreated.

Accordingly, there is a need for a benefit agent containing deliveryparticle that provides improved benefit agent delivery efficiency.

SUMMARY OF THE INVENTION

The present invention relates to benefit agent containing deliveryparticles comprising a core material and a wall material that at leastpartially surrounds the core material. The present invention alsorelates to compositions comprising said particles, and processes formaking and using such particles and compositions.

Example 8 Production of Spray Dried Microcapsule

1200 g of perfume microcapsule slurry, containing one or more of thevariants of microcapsules disclosed in the present specification, ismixed together with 700 g of water for 10 minutes using an IKA Eurostarmixer with R1382 attachment at a speed of 180 rpm. The mixture is thentransferred over to a feeding vessel to be spray dried in a 1.2 mdiameter Niro Production Minor. The slurry is fed into the tower using aWatson-Marlow 504U peristaltic pump and atomised using a 100 mm diameterrotary atomiser run at 18000 rpm, with co-current air flow for drying.The slurry is dried using an inlet temperature of 200° C. and outlettemperature of 95° C. to form a fine powder. The equipment used thespray drying process may be obtained from the following suppliers: IKAWerke GmbH & Co. KG, Janke and Kunkel—Str. 10, D79219 Staufen, Germany;Niro A/S Gladsaxevej 305, P.O.
